.LIllTUS'IAlBLEy WINDOW-SCREEN.

Applicationrfled August 14, 1917.

To all whom z't may concern:

Be it known that I, CHARLES V. STEWART, a citizen of the United States, residing at Santa Cruz, inthe county of Santa Cruz and State of California, have invented new and useful Improvements in Adjustable Window-Screens, of which the following is a specification.

The present invention relates to improvements in the construction of window screens.

The primary object of the invention is to simplify and improve .the existing art by producing an adjustable window screen so constructed that the component parts thereof, reinforce one another; one wherein the lapping sections are brought into close contact with each otherso that iiies or small insects cannot enter therebetween, and also one in which the same will so engage in the window casingand be so engaged by the sash and the casing lowered upon the said screen, as to effect a perfect joint therebetween which will also prevent the entrance of insects.

It is a further object of the invention to produce an adjustable window screen comprising similar parts each in the nature of a wooden frame, to secure to the frame metallic plates which lap the joints provided between the parts constituting the frames to reinforce the said frames and atthe same time to vreceive the screening, two of the oppositely disposed plates on each of the frames being extended beyond the edges of the said frames, the said extensions on one of the frames being bent upon themselves to provide guide ways for the extensions on the other frame, and wherein a single thickness of metal constituting what may be termed a knife edge is arranged for free sliding in the said guide ways.

Other objects and advantages will appear as the nature of the invention is more fully understood, reference being had to the accompanying drawings, in which,

My improved screen, las illustrated in Fig.

eoY

1 of the drawings, is designed to be received f in the window casing, the same being adjustable, may be brought to readily accommodate itself in the said casing, and the upper edge of the said screen is engaged by the lower sash of the casing. As will hereinafter appear, the engagement of the screen with the walls of the casing and its engagement by the window sash is such as to provide no space or gap between the contacting surfaces so that small insects can enter therebetween. 1t will also appear as the description progresses that the lap sections, comprising the screen so contact with each other that no space is left therebetween for the entrance of insects. Y

Referring now to the drawings in detail, the screen sections are indicated by the numerals 10 and 11 respectively. Each of the sections comprises a substantially rectangular wooden frame, the longitudinal members 12-whereof being of a greater width than the transverse or end members 13, and the longitudinal yor side members 1Q, having their ends engaged by the inner faces of the end members 13, suitable securing means, such as nails 14 being driven through the end members 13 and entering the side members 12. As the members 12 and 13 are cut in equal lengths respectively, it will be apparent that the frames, for the sections l() and 11, may be easily and quickly assembled. If desired, the contacting portions of the side and end members may be provided with interengaging elements as for instance, tongues and grooves, but, as the screen or netting serves to reinforce theV wooden frames and as the metallic plates, hereinafter to be referred to, effectively compress the frames at the connecting ends thereof, and still again, as it is one of the primary objects to produce a device which shall be simple, cheap and readily constructed, the nails 14 have been found amply sufiicient in the construction of the frames. The wire netting for each of the screens is indicated by the numerals 15-15, the same beino laid over one of the faces of the said frames, and secured thereto by small brads 16 that pass through longitudinal or side plates l-17 and transverse or end plates wfwooden .frames materially reinforcing thek l copi'es'ot. this patent maybe obtained for I able Y A f frames, ybut the Yend end members 418, the respective longitudinal plates being arranged over the longitudinal members 12 Y and the respective endplates being arranged over thevvrespective end membersliofthe wooden frames.

The longitudinal side ,plates 12 have their edges extending a suitdistance .beyond theouter edges of the .longitudinal Vmembers 12 of the Wooden plates 18 are of/a width approximately equaling the width of' the of thewoodenframes. extending edges of the' plates 17 on the frame section 10 are bent upon themselves l.providing substantially U-shaped waysV 19 which receive the projecting, edgesof the plates 17 of the frame section 11, whereby to v permitV of the ready slidable adjustment Vof the said section 11 over the section 10.
